How can I add electrical outlets to my house?

It is very easy to add outlets from existing outlets. Buy additional outlets and open the box of the existing outlets and connect the new outlets to the existing outlets through 2 square mm wire to the required length and fix the new outlets.

You will need to hire a licensed electrician if you want more electrical outlets in your house. Adding outlets is a relatively major job, and it is very unsafe to try to do your own wiring if you do not have proper training. In addition to safety concerns, wiring done by a non-electrician is not up to code.
